创建工具提示win32 api（Just API不是MFC） [英] Create tooltip win32 api (Just API not MFC)

问题描述

嘿每一个人！

我有丰富的编辑（只显示段落文字）

当我通过移动鼠标选择文本时，我想显示此选定的文本通过使用消息框屁股代码：

Hey every one!
I have a rich edit (only show paragraph text)
When i select a text by move mouse, i want to show this selected text by using message box ass following code:

case WM_KEYDOWN:
    if (wParam == VK_RETURN) 
    {
        wchar_t *wcWordSelect = new wchar_t[200];
	SendMessage(hWnd, EM_GETSELTEXT, SCF_SELECTION, (LPARAM)wcWordSelect);
	MessageBox(NULL, wcWordSelect, L"MSG", NULL);
    }
    break ;

但是我的任务是通过使用工具提示选择显示

请帮我用工具提示显示这个文字

我知道如何为按钮，气球工具栏制作工具提示但我不知道如何做我的任务

推荐答案

A MessageBox 不是很有用，因为它需要用户操作才能关闭它。请查看 MSDN文档 [< a href =http://msdn.microsoft.com/en-gb/library/windows/desktop/bb760252(v=vs.85).aspx\"target =_ blanktitle =New Window> ^ ]。

A MessageBox is not very useful as it requires action from the user to close it. Take a look at the MSDN documentation[^] on tooltips.

是的，我可以显示按钮的工具提示，例如：

Yes, i can show tooltip for a button such as:

case WM_NOTIFY:
{
    switch (((LPNMHDR) lParam)->code)
    {
        case TTN_NEEDTEXT:
        {
            LPTOOLTIPTEXT lptttext;
            lptttext = (LPTOOLTIPTEXT) lParam;
            lptttext->hinst = g_hInst;
            switch(lptttext->hdr.idFrom)
            {
            case ID_BUTTON1:
                {
                    lptttext->lpszText = L"Tooltip button 1";
                }break;
            }
        }
    }
}
break;

这里的代码使用消息框显示所选文本（我创建了一个丰富的编辑控件的程序）

And the code below here show the selected text using message box (I create a procedure for rich edit controll)

LRESULT FAR PASCAL RichEditProc(HWND hWnd,
                                UINT Message,
                                WPARAM wParam,
                                LPARAM lParam)
{
    wchar_t *wcWordSelect = new wchar_t[MAX_LENG_WORD];
    switch(Message)
    {
    case WM_CHAR:
        //Process this message to avoid message beeps.
        if ((wParam == VK_RETURN) || (wParam == VK_TAB))
        {
            //Do Something
            return 0;
        }
        break;
    case  WM_RBUTTONDOWN:
        {
            SendMessage(hWnd, EM_GETSELTEXT, SCF_SELECTION, (LPARAM)wcWordSelect);
            MessageBox(NULL, wcWordSelect, L"MSG", NULL);
            CreateToolTipForRect(hWnd);
        }
        break;
    case WM_KEYDOWN:
        if (wParam == VK_RETURN)
        {
            SendMessage(hWnd, EM_GETSELTEXT, SCF_SELECTION, (LPARAM)wcWordSelect);
            MessageBox(NULL, wcWordSelect, L"MSG", NULL);
            return 0;
        }
        break ;

    default:
        break;
    }
    return CallWindowProc((WNDPROC)lpfnOldWndProc, hWnd, Message, wParam, lParam);
}

我的问题是：如何使用工具提示，使用消息框显示'' wcWordSelect ''变量？

感谢您的帮助!!

My QUESTION is: how can i use tooltip insted of using message box to show ''wcWordSelect'' variable?
Thank for your help!!
